The triple warmer 17 point lies just behind the
mandible in the hollow spot under the ear. This
point is located directly over the root of the seventh cranial nerve (facial
nerve) Striking this point can cause a loss
of consciousness or increased parasympathetic effects on the heart. In addition,
the facial
nerve has direct connections to the vagus and trigeminal nerves, which have been linked to cardiac arrest
when stimulated. Thus, stimulation of the
triple warmer 17 point can stimulate the trigeminal and vagus nerves leading to
syncope (fainting) or cardiac arrest in a susceptible individual. Furthermore,
blows to this area have been associated traumatic subarachnoid hemorrhages and
instant death. There are numerous autopsies that have a bruise in this area and
traumatic subarachnoid hemorrhages. The mechanism is believed to involve
rotation of the head in combination with translation of the C2 vertebrate
because part of this vertebrate is accessible under this point.
